> It found carbon dioxide is accumulating faster than at any time in human history, with concentrations having risen by more than 10% in just two decades. "Another year, another record," said Celeste Saulo, secretary-general of the WMO. "This should set alarm bells ringing among decision makers." The increase was driven by humanity's "stubbornly high" burning of fossil fuels, the WMO found, and made worse by big wildfires and a possible drop in the ability of trees to absorb carbon. The concentration of CO2 reached 420 parts per million (ppm) in 2023, the scientists observed. The level of pollution is 51% greater than before the Industrial Revolution, when people began to burn large amounts of coal, oil and fossil gas.

Humans have noticable cognitive impairment as CO2 approaches 1000ppm. We like to stay inside a lot, with other people, all exhaling CO2 and increasing the amount present. Typically we deal with this by bringing in outside air. Such systems are usually designed to keep CO2 below 800ppm, but those designs include the assumption that 'fresh' air is ~400ppm.
Basically, if (as) CO2 in the atmosphere goes up, we're going to get a lot dumber or spend a lot of money increasing HVAC capacity and adding CO2 scrubbe

The main "planet heating pollutant" in the atmosphere is carbon dioxide. The carbon dioxide concentration in the atmosphere is increasing, has been increasing, and continues to be increasing; and hence every year is a "record level."

Planet heating pollutants disappear at an incredibly slow rate. They will keep hitting record levels for many MANY years to come, year over year. Planet heating pollutants also hit record levels in 2020 while the world massively scaled back an insane amount of industry and consumption during COVID. That alone should tell you that this is not newsworthy.
Newsworthy would be this obvious trend doing something different.

People are instinctively short term focused. It is in our DNA. If you die of starvation/dehydration in the next few days it doesn't matter what happens a month from now. Things you can see or feel also make much more of an impact that abstract things like "You'll have heart disease 30 yrs from now." People will eat poorly and not move then act surprised when they are falling apart later. The problem is once X happens it can usually be far more expensive or even impossible to reverse the damage.

Home-based analogies seem to work well at explaining these concepts to normal people. Tell them to imagine being trapped in a house that's on fire. Escape is not a real option, so you gotta put it out. And what's the first step to putting out a fire? Stop lighting more ones! And what's an internal combustion engine but a machine that constantly lights fires?
Since I started explaining it like this, I'm pleasantly surprised how many people get it.

Pollution Controls For Cargo Ships [1]Made Global Warming Worse [hackaday.com]
According to the [2] paper [nature.com] from the article, abruptly reducing the sulfur emissions from global shipping resulted in a 0.2 W/M^2 increase in the amount of radiative (from the sun) energy over the entire ocean, which is predicted to double the global warming rate in the 2020's as compared to the rate in the 1980s.

You are proposing one solution, then saying you don't like that solution. (This is called a "strawman argument.") So: propose another one.

For comparison, the total anthropogenic forcing (primarily due to carbon dioxide) is currently about 2.8 W/m^2, so that 0.2 W/m^2 is about 7% of the warming. It's the other 93% of the warming we have to deal with... because it is is not constant, but is increasing with time.

Be careful here. The article didn't say it would double the rate of all global warming, it said that removing the cooling effect has doubled the rate of warming over the 2020s (i.e., that removing the cooling effect equaled the added h

Yep, this is why it is a hard problem. It can't be solved by what any single individual does. In essence, the atmosphere of the planet is a commons (no one owns it), and the problem of the effects of what people put into the atmosphere is a [1]tragedy of the commons [wikipedia.org].

I'm not disputing what's going on, but dangerous statements like, "The level of pollution is 51% greater than before the Industrial Revolution" carry a serious risk: when our children and their children reach a point of stability, they'll start reversing things to before the start of the Industrial Revolution, a climate period also known as the Little Ice Age.
